Vir Biotechnology Presents New Data on VIR-2482, the Company’s Investigational Monoclonal Antibody for the Prevention of Influenza A, at IDWeek 2020
– Preclinical data show VIR-2482 has broad neutralizing potential against
all major strains of influenza A from the last 100 years –
– Extended half-life observed in Phase 1 demonstrates potential for once-per-season dosing –
– Claims-based analysis highlights the high hospitalization rates and elevated costs among high-risk elderly patients, reinforcing need for new approaches to prevention –
“Despite widespread influenza vaccination, the elderly in the
The two abstracts accepted for poster presentation include:
- Preliminary, blinded pharmacokinetic and safety data from the first-in-human, randomized, placebo-controlled Phase 1 study, which demonstrate that intramuscular dosing of VIR-2482 was well tolerated among healthy volunteers at doses up to 1,800mg (Abstract #631). The preliminary pharmacokinetic profile also shows a prolonged half-life, which could enable once-per-season dosing.
- Preclinical data, which show that VIR-2482 has broad binding and neutralizing potential against all major strains of influenza A, including pandemic strains, from the last 100 years (Abstract #1231). Additionally, VIR-2482 administered prophylactically 24 hours prior to lethal doses of influenza significantly reduced morbidity and prevented mortality in mouse models.
A separate claims-based analysis accepted for oral presentation demonstrates the significant health and economic impact of influenza A on elderly patients (>65 years old) with comorbidities (Abstract #86). According to an analysis of insurance claims data from the IQVIA PharMetrics® Plus database (

VIR-2482 is an intramuscularly administered influenza A-neutralizing monoclonal antibody. In vitro, it has been shown to cover all major strains of influenza A that have arisen since the 1918 Spanish influenza pandemic. VIR-2482 is designed as a universal prophylactic for influenza A. It has the potential to overcome the limitations of current influenza vaccines and lead to meaningfully higher levels of protection due to its broad strain coverage and because it does not rely on an individual to create their own protective antibody response. VIR-2482 has been half-life engineered so that a single dose has the potential to last the entire influenza season, which is typically five to six months long.

Actual results may differ materially from these forward-looking statements. Forward-looking statements contained in this press release include statements regarding the potential benefits of VIR-2482, including its ability to broadly neutralize against all major strains of influenza A, its high-level effector function and binding capability and its extended half-life, the potential of VIR-2482 in treating high-risk, elderly patients, the potential of VIR-2482 as a universal prophylaxis for influenza A and the health and economic implications of influenza A on elderly patients. Many factors may cause differences between current expectations and actual results including unexpected safety or pharmacokinetic data observed during preclinical or clinical studies, challenges in treating influenza A, difficulty in collaborating with other companies or government agencies, and challenges in accessing manufacturing capacity. Other factors that may cause actual results to differ from those expressed or implied in the forward-looking statements in this press release are discussed in Vir’s filings with the U.S. Securities and Exchange Commission, including the section titled “Risk Factors” contained therein.
